An inquiry set up by the Indian government on Thursday found former foreign minister Natwar Singh and his son guilty of misconduct over the UN oil-for-food scheme in Iraq, reports said. The inquiry, headed by retired Supreme Court judge R S Pathak, decided that both Natwar Singh and his son Jagat Singh were guilty of wrongdoing, the Press Trust of India news agency reported. But no money from the sale of the Iraqi oil has been traced to either of them even though two of Jagat Singh's friends were found to have made money from the deal, another report said. News channel NDTV said the investigative commission found the father and son guilty of misusing their positions in the Congress party to secure the oil contracts. But it said the probe exonerated Congress-also named in a UN report as a non-contractual beneficiary in the scam-of any wrongdoing. The reports followed Pathak handing over his 110-page report to Prime Minister Manmohan Singh in New Delhi.
